The utilization of waste tire rubber (WTR) in concrete is an environmentally sustainable solution that has garnered significant interest recent years. However, incorporating WTR can lead to a reduction its mechanical properties. This study proposes life-cycle assessment-based method for the simultaneous evaluation environmental and aspects concrete. converts generated impacts into scores defines series scenarios employ pre-coating techniques enhance properties assessment results using proposed reveal that, although significantly reduces strength, it also substantially decrease impacts-by up 75%-compared scenario ordinary combined with landfilling.
